A sealing material particularly suitable for producing liquid crystal display panels of which the base plates are made of flexible polymer film, which sealing material comprises a reaction-setting type polymer containing siloxane bonds in the molecules, which polymer is represented by the following general formula <IMAGE> wherein R represents a lower alkyl group, and X1, X2, X3, X4, X5, X6 and X7 independently represent radicals selected from the group consisting of hydroxy, acetoxy, alkoxy, hydrogen, vinyl, epoxy, amino, glycol, phenyl, fluorinated alkyl and lower alkyl, and at least one of X1 through X7 is a radical selected from the group consisting of hydroxy, acetoxy, alkoxy, hydrogen, vinyl, epoxy, amino and glycol, and n represents an integer of 5 to 10000. Since sealing material has high sealing strength for the polymer film over a long period of time and is free from solvents, the liquid crystal, the orientation processed films, the transparent electrodes and the base plates of the liquid display panels are not caused to deteriorate by this sealing material.
